Can't print the skirt properly

[osterac]

So I'm not sure what it was that I did but the printer now only needs some adjustments to steps per mm, but I'm having trouble figuring that out. The ender 4 source code is posted here and I tried using the Arduino IDE to edit the configuration.h file and insert the new steps per mm values, but when I try to upload to the printer, it says "too many decimal points in number." If I try to get the board info from my printer it says this:
BN: Unknown board
VID: 0403
PID: 6001
SN: Upload any sketch to obtain it
The options to adjust steps per mm from within the printer's UI are disabled. Any thoughts on what to do?
Thanks so much
*EDIT*
it was a typo.
Now it says
"Error compiling for board Arduino Mega ADK."
*EDIT2*
Here's the full log
